Thinking in C++ patiently and methodically explores the issues of when and how to use inlines, references, operator overloading, inheritance and dynamic objects, as well as advanced topics such as the proper use of templates, exceptions and multiple inheritance. The entire effort is woven in a fabric that includes Eckel’s own philosophy of object and program design. A must for every C++ developer’s bookshelf, Thinking in C++ is the one C++ book you must have if you’re doing serious development with C++.

利用單片機制作音樂播放器的課程設計報告. 作為單片機的重要硬件資源之一，利用定時器可以產生各種固定頻率的方波信號，也可以產生包括“Do“、“Re“、“Me“--等音階在內的各種頻率聲音。在此設計中我們采用12MHz的晶振，產生的頻率信號即音樂信號由P3．7口輸出，信號經過放大后由喇叭發出聲音。

本書分為四大篇。第一篇提出學習MFC程序設計之前的必要基礎，包括Widnows程序的基本觀念以及C++的高階議題。“學前基礎”是相當主觀的認定，不過，甚于我個人的學習經驗以及教學經驗，我的挑選應該頗具說服力。第二篇介紹Visual C++整合環境開發工具。本篇只不過是提綱挈領而已，并不企圖取代 Visual C++使用手冊。然而對于軟件使用的老手，此篇或已足以讓您掌握Visual C++整合環境。工具的使用雖然談不上學問，但在視覺化軟件開發過程中扮演極重角色，切莫小覷它。 第三篇介紹application framework的觀念，以及MFC骨干程序，所謂骨干程序，是指Visual C++的工具AppWizard所產生出來的程序碼。當然，AppWizard會根據你的選項做出不同的程序碼，我所據以解說的，是大眾化選項下的產品。 第四篇以微軟公司附于Visual C++光碟片上的一個范例程序Scribble為主軸，一步一步加上新的功能。并在其間深入介紹Runtime Type Information（RTTI）、Dynamic Creation、Persistence（Serialization）、Message Mapping、Command Routing等核心技術。這些技術正是其他書籍最缺乏的部分。此篇之最后數章則脫離Scribble程序，另成一格。 本書內含光盤一片，書中所有原始碼與可執行文件盡在其中。

基于OFDM的無線寬帶系統仿真It contains mainly two parts, i.e. link-level simulator and system-level simulator. Link-level simulator focus on a single-cell single-user scenario, where signal is transmitted from tx, and estimated at rx. Comparing the difference in tx/rx signal, the error rate can be found out. The output of the link-level simulator is the BLER/BER vs. SNR mapping table, that can be used for the system-level simulation. System-level simulator focus on a multi-cell multi-user scenario. For the sake of simplicity, it takes the mapping table aquired in the link-level simulation, measure the actural SNR, and finds the corresponding error rate.

This project aim was to build wireless software modem for data communication between two computers using an acoustic interface in the voice frequency range (20Hz– 20,000Hz). The transmitting antenna is a speaker (frequency response of: 90Hz – 20,000Hz) and the receiving antenna is a microphone (frequency response of: 100Hz – 16,000Hz). The test files used as information files were text files. This goal was attained both in an incoherent scheme and in a coherent scheme. Build under Matlab code, our modem uses OFDM (orthogonal frequency division multiplexing) modulation, synchronization by LMS sequence, channel estimation (no equalizer) via pilot tones. The symbols are either PSK or ASK for a constellation size of 2 or 4. To optimize the probability of error, these symbols were mapped using Gray mapping. Report
